+/**
+ * SECTION: WebKitFileChooserRequest
+ * @Short_description: A request to open a file chooser
+ * @Title: WebKitFileChooserRequest
+ * @See_also: #WebKitWebView
+ *
+ * Whenever the user interacts with an &lt;input type='file' /&gt;
+ * HTML element, WebKit will need to show a dialog to choose one or
+ * more files to be uploaded to the server along with the rest of the
+ * form data. For that to happen in a general way, instead of just
+ * opening a #GtkFileChooserDialog (which might be not desirable in
+ * some cases, which could prefer to use their own file chooser
+ * dialog), WebKit will fire the #WebKitWebView::run-file-chooser
+ * signal with a #WebKitFileChooserRequest object, which will allow
+ * the client application to specify the files to be selected, to
+ * inspect the details of the request (e.g. if multiple selection
+ * should be allowed) and to cancel the request, in case nothing was
+ * selected.
+ *
+ * In case the client application does not wish to handle this signal,
+ * WebKit will provide a default handler which will asynchronously run
+ * a regular #GtkFileChooserDialog for the user to interact with.
